The existing wall was damaged during the Aug. 20 train derailment, which took the lives of two Ellicott City teenagers. While CSX and the county have completed repairs since the accident, work on the retaining wall was left until the spring.

"We apologize for any inconvenience that might be caused by this projects," Howard County Executive Ken Ulman said in a statement. 'We are working with CSX so that construction is completed as quickly as possible and we can get Ellicott City back to normal fast."

Construction will take place between 7 a.m. and 5 p.m. on most weekdays.
